an SSL connection</p>
<p>QSslConfiguration is used by Qt networking classes to relay
information about an open SSL connection and to allow the
application to control certain features of that connection.</p>
<p>The settings that QSslConfiguration currently supports are:</p>
<ul>
<li>The SSL/TLS protocol to be used</li>
<li>The certificate to be presented to the peer during connection
and its associated private key</li>
<li>The ciphers allowed to be used for encrypting the
connection</li>
<li>The list of Certificate Authorities certificates that are used
to validate the peer's certificate</li>
</ul>
<p>These settings are applied only during the connection handshake.
Setting them after the connection has been established has no
effect.</p>
<p>The state that QSslConfiguration supports are:</p>
<ul>
<li>The certificate the peer presented during handshake, along with
the chain leading to a CA certificate</li>
<li>The cipher used to encrypt this session</li>
</ul>
<p>The state can only be obtained once the SSL connection starts,
but not necessarily before it's done. Some settings may change
during the course of the SSL connection without need to restart it
(for instance, the cipher can be changed over time).</p>
<p>State in QSslConfiguration objects cannot be changed.</p>
<p>QSslConfiguration can be used with <a href="qsslsocket.html">QSslSocket</a> and the Network Access API.</p>
<p>Note that changing settings in QSslConfiguration is not enough
to change the settings in the related SSL connection. You must call
setSslConfiguration on a modified QSslConfiguration object to
achieve that. The following example illustrates how to change the
protocol to TLSv1 in a <a href="qsslsocket.html">QSslSocket</a>
object:</p>
<pre class="cpp">
 <span class="type">QSslConfiguration</span> config <span class="operator">=</span> sslSocket<span class="operator">.</span>sslConfiguration();
 config<span class="operator">.</span><a href="qsslconfiguration.html#setProtocol">setProtocol</a>(<span class="type"><a href="qssl.html">QSsl</a></span><span class="operator">.</span>TlsV1);
 sslSocket<span class="operator">.</span>setSslConfiguration(config);
</pre>
<p><a href="qsslsocket.html">QSslSocket</a>, <a href="qnetworkaccessmanager.html">QNetworkAccessManager</a>, <a href="qsslsocket.html#sslConfiguration">QSslSocket.sslConfiguration</a>(),
<a href="qsslsocket.html#setSslConfiguration">QSslSocket.setSslConfiguration</a>()</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QSslConfiguration" />QSslConfiguration.__init__ (<i>self</i>)</h3><p>Constructs an empty SSL configuration. This configuration
contains no valid settings and the state will be empty. <a href="qsslconfiguration.html#isNull">isNull</a>() will return true after
this constructor is called.</p>
<p>Once any setter methods are called, <a href="qsslconfiguration.html#isNull">isNull</a>() will return false.</p>


<h3 class="fn"><a name="QSslConfiguration-2" />QSslConfiguration.__init__ (<i>self</i>, <a href="qsslconfiguration.html">QSslConfiguration</a>&#160;<i>other</i>)</h3><p>Copies the configuration and state of <i>other</i>. If
<i>other</i> is null, this object will be null too.</p>


<h3 class="fn"><a name="caCertificates" />list-of-QSslCertificate QSslConfiguration.caCertificates (<i>self</i>)</h3><p>Returns this connection's CA certificate database. The CA
certificate database is used by the socket during the handshake
phase to validate the peer's certificate. It can be modified prior
to the handshake with <a href="qsslconfiguration.html#setCaCertificates">setCaCertificates</a>(),
or with <a href="qsslsocket.html">QSslSocket</a>'s <a href="qsslsocket.html#addCaCertificate">addCaCertificate()</a> and
<a href="qsslsocket.html#addCaCertificates">addCaCertificates()</a>.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#setCaCertificates">setCaCertificates</a>().</p>


<h3 class="fn"><a name="ciphers" />list-of-QSslCipher QSslConfiguration.ciphers (<i>self</i>)</h3><p>Returns this connection's current cryptographic cipher suite.
This list is used during the handshake phase for choosing a session
cipher. The returned list of ciphers is ordered by descending
preference. (i.e., the first cipher in the list is the most
preferred cipher). The session cipher will be the first one in the
list that is also supported by the peer.</p>
<p>By default, the handshake phase can choose any of the ciphers
supported by this system's SSL libraries, which may vary from
system to system. The list of ciphers supported by this system's
SSL libraries is returned by <a href="qsslsocket.html#supportedCiphers">QSslSocket.supportedCiphers</a>().
You can restrict the list of ciphers used for choosing the session
cipher for this socket by calling <a href="qsslconfiguration.html#setCiphers">setCiphers</a>() with a subset
of the supported ciphers. You can revert to using the entire set by
calling <a href="qsslconfiguration.html#setCiphers">setCiphers</a>() with the list
returned by <a href="qsslsocket.html#supportedCiphers">QSslSocket.supportedCiphers</a>().</p>

<h3 class="fn"><a name="defaultConfiguration" /><a href="qsslconfiguration.html">QSslConfiguration</a> QSslConfiguration.defaultConfiguration ()</h3><p>Returns the default SSL configuration to be used in new SSL
connections.</p>
<p>The default SSL configuration consists of:</p>
<ul>
<li>no local certificate and no private key</li>
<li>protocol SecureProtocols (meaning either TLS 1.0 or SSL 3 will
be used)</li>
<li>the system's default CA certificate list</li>
<li>the cipher list equal to the list of the SSL libraries'
supported SSL ciphers</li>
</ul>

and <a href="qsslconfiguration.html#setDefaultConfiguration">setDefaultConfiguration</a>().</p>


<h3 class="fn"><a name="isNull" />bool QSslConfiguration.isNull (<i>self</i>)</h3><p>Returns true if this is a null <a href="qsslconfiguration.html">QSslConfiguration</a> object.</p>
<p>A <a href="qsslconfiguration.html">QSslConfiguration</a> object
is null if it has been default-constructed and no setter methods
have been called.</p>

<h3 class="fn"><a name="localCertificate" /><a href="qsslcertificate.html">QSslCertificate</a> QSslConfiguration.localCertificate (<i>self</i>)</h3><p>Returns the certificate to be presented to the peer during the
SSL handshake process.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#setLocalCertificate">setLocalCertificate</a>().</p>


<h3 class="fn"><a name="peerCertificate" /><a href="qsslcertificate.html">QSslCertificate</a> QSslConfiguration.peerCertificate (<i>self</i>)</h3><p>Returns the peer's digital certificate (i.e., the immediate
certificate of the host you are connected to), or a null
certificate, if the peer has not assigned a certificate.</p>
<p>The peer certificate is checked automatically during the
handshake phase, so this function is normally used to fetch the
certificate for display or for connection diagnostic purposes. It
contains information about the peer, including its host name, the
certificate issuer, and the peer's public key.</p>
<p>Because the peer certificate is set during the handshake phase,
it is safe to access the peer certificate from a slot connected to
the <a href="qsslsocket.html#sslErrors">QSslSocket.sslErrors</a>()
signal, <a href="qnetworkreply.html#sslErrors">QNetworkReply.sslErrors</a>()
signal, or the <a href="qsslsocket.html#encrypted">QSslSocket.encrypted</a>() signal.</p>
<p>If a null certificate is returned, it can mean the SSL handshake
failed, or it can mean the host you are connected to doesn't have a
certificate, or it can mean there is no connection.</p>
<p>If you want to check the peer's complete chain of certificates,
use <a href="qsslconfiguration.html#peerCertificateChain">peerCertificateChain</a>()
to get them all at once.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#peerCertificateChain">peerCertificateChain</a>(),

<a href="qnetworkreply.html#ignoreSslErrors">QNetworkReply.ignoreSslErrors</a>().</p>


<h3 class="fn"><a name="peerCertificateChain" />list-of-QSslCertificate QSslConfiguration.peerCertificateChain (<i>self</i>)</h3><p>Returns the peer's chain of digital certificates, starting with
the peer's immediate certificate and ending with the CA's
certificate.</p>
<p>Peer certificates are checked automatically during the handshake
phase. This function is normally used to fetch certificates for
display, or for performing connection diagnostics. Certificates
contain information about the peer and the certificate issuers,
including host name, issuer names, and issuer public keys.</p>
<p>Because the peer certificate is set during the handshake phase,
it is safe to access the peer certificate from a slot connected to
the <a href="qsslsocket.html#sslErrors">QSslSocket.sslErrors</a>()
signal, <a href="qnetworkreply.html#sslErrors">QNetworkReply.sslErrors</a>()
signal, or the <a href="qsslsocket.html#encrypted">QSslSocket.encrypted</a>() signal.</p>
<p>If an empty list is returned, it can mean the SSL handshake
failed, or it can mean the host you are connected to doesn't have a
certificate, or it can mean there is no connection.</p>
<p>If you want to get only the peer's immediate certificate, use
<a href="qsslconfiguration.html#peerCertificate">peerCertificate</a>().</p>

<a href="qnetworkreply.html#ignoreSslErrors">QNetworkReply.ignoreSslErrors</a>().</p>


<h3 class="fn"><a name="peerVerifyDepth" />int QSslConfiguration.peerVerifyDepth (<i>self</i>)</h3><p>Returns the maximum number of certificates in the peer's
certificate chain to be checked during the SSL handshake phase, or
0 (the default) if no maximum depth has been set, indicating that
the whole certificate chain should be checked.</p>
<p>The certificates are checked in issuing order, starting with the
peer's own certificate, then its issuer's certificate, and so
on.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#setPeerVerifyDepth">setPeerVerifyDepth</a>()
and <a href="qsslconfiguration.html#peerVerifyMode">peerVerifyMode</a>().</p>


<h3 class="fn"><a name="peerVerifyMode" /><a href="qsslsocket.html#PeerVerifyMode-enum">QSslSocket.PeerVerifyMode</a> QSslConfiguration.peerVerifyMode (<i>self</i>)</h3><p>Returns the verify mode. This mode decides whether <a href="qsslsocket.html">QSslSocket</a> should request a certificate from
the peer (i.e., the client requests a certificate from the server,
or a server requesting a certificate from the client), and whether
it should require that this certificate is valid.</p>
<p>The default mode is AutoVerifyPeer, which tells <a href="qsslsocket.html">QSslSocket</a> to use VerifyPeer for clients,
QueryPeer for servers.</p>

<h3 class="fn"><a name="sessionCipher" /><a href="qsslcipher.html">QSslCipher</a> QSslConfiguration.sessionCipher (<i>self</i>)</h3><p>Returns the socket's cryptographic <a href="qsslcipher.html">cipher</a>, or a null cipher if the connection
isn't encrypted. The socket's cipher for the session is set during
the handshake phase. The cipher is used to encrypt and decrypt data
transmitted through the socket.</p>
<p>The SSL infrastructure also provides functions for setting the
ordered list of ciphers from which the handshake phase will
eventually select the session cipher. This ordered list must be in
place before the handshake phase begins.</p>

<h3 class="fn"><a name="setCaCertificates" />QSslConfiguration.setCaCertificates (<i>self</i>, list-of-QSslCertificate&#160;<i>certificates</i>)</h3><p>Sets this socket's CA certificate database to be
<i>certificates</i>. The certificate database must be set prior to
the SSL handshake. The CA certificate database is used by the
socket during the handshake phase to validate the peer's
certificate.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#caCertificates">caCertificates</a>().</p>


<h3 class="fn"><a name="setCiphers" />QSslConfiguration.setCiphers (<i>self</i>, list-of-QSslCipher&#160;<i>ciphers</i>)</h3><p>Sets the cryptographic cipher suite for this socket to
<i>ciphers</i>, which must contain a subset of the ciphers in the
list returned by supportedCiphers().</p>
<p>Restricting the cipher suite must be done before the handshake
phase, where the session cipher is chosen.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#ciphers">ciphers</a>() and <a href="qsslsocket.html#supportedCiphers">QSslSocket.supportedCiphers</a>().</p>


<h3 class="fn"><a name="setDefaultConfiguration" />QSslConfiguration.setDefaultConfiguration (<a href="qsslconfiguration.html">QSslConfiguration</a>&#160;<i>configuration</i>)</h3><p>Sets the default SSL configuration to be used in new SSL
connections to be <i>configuration</i>. Existing connections are
not affected by this call.</p>
<p><b>See also</b> <a href="qsslsocket.html#supportedCiphers">QSslSocket.supportedCiphers</a>()
and <a href="qsslconfiguration.html#defaultConfiguration">defaultConfiguration</a>().</p>


<h3 class="fn"><a name="setLocalCertificate" />QSslConfiguration.setLocalCertificate (<i>self</i>, <a href="qsslcertificate.html">QSslCertificate</a>&#160;<i>certificate</i>)</h3><p>Sets the certificate to be presented to the peer during SSL
handshake to be <i>certificate</i>.</p>
<p>Setting the certificate once the connection has been established
has no effect.</p>
<p>A certificate is the means of identification used in the SSL
process. The local certificate is used by the remote end to verify
the local user's identity against its list of Certification
Authorities. In most cases, such as in HTTP web browsing, only
servers identify to the clients, so the client does not send a
certificate.</p>
<p><b>See also</b> <a href="qsslconfiguration.html#localCertificate">localCertificate</a>().</p>


<h3 class="fn"><a name="setPeerVerifyDepth" />QSslConfiguration.setPeerVerifyDepth (<i>self</i>, int&#160;<i>depth</i>)</h3><p>Sets the maximum number of certificates in the peer's
certificate chain to be checked during the SSL handshake phase, to
<i>depth</i>. Setting a depth of 0 means that no maximum depth is
set, indicating that the whole certificate chain should be
checked.</p>
<p>The certificates are checked in issuing order, starting with the
peer's own certificate, then its issuer's certificate, and so
on.</p>

<h3 class="fn"><a name="setPeerVerifyMode" />QSslConfiguration.setPeerVerifyMode (<i>self</i>, <a href="qsslsocket.html#PeerVerifyMode-enum">QSslSocket.PeerVerifyMode</a>&#160;<i>mode</i>)</h3><p>Sets the verify mode to <i>mode</i>. This mode decides whether
<a href="qsslsocket.html">QSslSocket</a> should request a
certificate from the peer (i.e., the client requests a certificate
from the server, or a server requesting a certificate from the
client), and whether it should require that this certificate is
valid.</p>
<p>The default mode is AutoVerifyPeer, which tells <a href="qsslsocket.html">QSslSocket</a> to use VerifyPeer for clients,
QueryPeer for servers.</p>

<h3 class="fn"><a name="setPrivateKey" />QSslConfiguration.setPrivateKey (<i>self</i>, <a href="qsslkey.html">QSslKey</a>&#160;<i>key</i>)</h3><p>Sets the connection's private <a href="qsslkey.html">key</a> to
<i>key</i>. The private key and the local <a href="qsslcertificate.html">certificate</a> are used by clients and
servers that must prove their identity to SSL peers.</p>
<p>Both the key and the local certificate are required if you are
creating an SSL server socket. If you are creating an SSL client
socket, the key and local certificate are required if your client
must identify itself to an SSL server.</p>

<h3 class="fn"><a name="setProtocol" />QSslConfiguration.setProtocol (<i>self</i>, <a href="qssl.html#SslProtocol-enum">QSsl.SslProtocol</a>&#160;<i>protocol</i>)</h3><p>Sets the protocol setting for this configuration to be
<i>protocol</i>.</p>
<p>Setting the protocol once the connection has already been
established has no effect.</p>
